Really nice!
I like them all 
rofl, nice
Like it
I think u can do a lot with PhotoShop
good job on the before and after photo.
it has given it that feel of motion.

Thanks 
The one with the car is really cool, how did you do it? (with wich options/tools whatever)
Some good manipulations there.
Agree ^^
Nice works.. I like the last one specially
Wow--that car looks really great 
I like them all to......especially the first one
i like the photomanipulation on the last one mate 
Nice stuff. Messing around with plugins can be fun.
Not a photomanip buff however. I think the last one could be improved a bit.
The first one is realy cool. Also you've done a great job with the car, realy giving it a feel of motion.
ya that one with the car is really cool...but my favorite is the flames or explosion type one...its cool lookin man..keep up the good work
last one is nice 
Go on and train your photoshop skills. They might help you, but don't stop here.
I dont want to narrow you work, but if you take a look at the first few
pictures, maybe you will agree with me that these are a bit empty
(i know this from my beginnings ^^), and well these are only a few
filters you combined to get a nice effect. (By the way the first, could
be nice as a wallpaper, maybe play a bit around with it (and enlarge!)).
But back to the main point.
Go further then having a (turbulent*1)
backroung and some text. Your aim should be to have a in its elements a
closed image. This could be done by a border or whatever.*2.
Ads are a good example to explain basic elements of graphics.
(and they show you ways to combine content with art/visuals/layout)
A few of the basic elements are you allready using: you use some bg
(maybe the bg shouldn't end beyond the image itself.*3)
you used some text what represent some kind of content.
(also you tried (and got it done) to make these two elements to fit
together (color-themes, font, etc..).
So whats more. You say: "couicsilver" maybe at this place you can add
something about it, some slogan for example. (just a very little sentence,
similar to ads). Now you add some 'design elements'*4.
Well i didn't want to write such a long comment, but for some reason
i thought i should give you this few tips and suggestions.
Often its a good training to make ad for some company/thing (maybe for ferrari?).
And again, don't handle a effect you got done as a final image,
maybe think about using this effect for something integrate it into something...
I hope you can find some help in my feedback and don't think
that i decry your work. Its ment as contructive feedback.

Notes, statements, declarations...
*1 - often a still, smooth background works 'fantastic'
*2 - try to stay 2D, often adding 3rd dimension ruins the structure, the good looking^^
*3 - your image is you workarea, not more and not less!, of course there exceptions
*4 - just colored boxes/squares for example (with alpha and a mask if you like)
Neat stuff you got there. Nothing very advanced, but everything was done very well.
wonderful work. I really like the car one, very good effects. I hope to see more from you
I agree with most of whats posted above and look froward to seeing more of your creations 
oh.. really Good creations ...
i like the first one more ... like jazrt said
give us a feel of motion and power
nice work ,,, keep on

Good work. I like the 4th one and the last one the best.
I too use Photoshop and hope to see more of your work.
I agree with silentpark, keep working and you'll create some REAL works one day. By the way, it's not difficult at all 
Wow, those are good good skills. Keep on working and here to what silentpark has to say.
(I wish I could do have of what you've done)
