Hi, Zatchara! I'm glad you opened up a shop here!
Few things I wanna critique.
First are the signatures you posted in the "created" section--

This looks really good, but the focal point is...I don't know, hard to look at. My eyes keep looking at the effects flowing out of him instead of at him. Sharpening him should help that.

The main thing here is that you covered up the face. That's generally something you shouldn't do, although here because of the effects you were using it makes sense. Your use of light is amazing, though.

It's really cool how you picked the four main colors and put those in those rectangles on the side. It makes a nice accent. Use of light here is pretty stunning as well, and I like how you used the bubble c4d, but not so it looked half transparent.
Alright, so next I'd like to talk about your header images, lol.
They're huge xD
The biggest limit to not be resized by
ZU is 670 width, but staying with 600 is generally safe. It would make your thread much easier to read and browse through if you knocked out that extra transparent space above and below the text, and then resized them down to 600 width.
All in all I'm glad you've opened a shop and I like your work, I hope you continue to produce works just as good!
