I've been wanting to comment on your stuff for a while now. But each time I'd be too lazy. hehe. But now I will take a bit of time to write you some critique.

You're a talented artist, that's for sure. You always surprise me with nice and original concepts. I think your weakness lies in technique. And I'm refering specifically to your colour usage.

Often your great drawings are ruined because of bad colour choices. And with that I mean that they are often too bright, nearly neon colours. I can understand this is some kind of stylistic choice, but this colour burn is just not working for me.

It's not only the brightness, but also the shades of the colours themselves. You always shade light blue with pure dark blue. Experiment a little! Interesting hues can bring so much to a piece. For example, try purple as a shade for blue. Or blue for a shade to green. This can have really nice effects. And it can make all the difference in the world. I'm certain it can make your art even better then it already is.

The only further comment I have further is that perhaps you draw too sketchy sometimes. Try defining the forms more. Study light and volume.

I hope it helps.
