Ooh what kind of shop are you opening?
Critique:
Background and overall colour balance are both really nice.
Your font choice isn't optimal. It works, but it could work better. The background is the strongest part of the image, maybe try to find a font that emulates it's shapes.
I'd suggest removing the bumpmap on the font too. 3D effects are often unnecessary if the surrounding composition is strong enough.
The render is too clean IMO. You have these neat smudgy blur effects at the corners, but kind of just a plopped on render.
You can consider overlaying some texture or smudging it or something.
Bottom left corner could use some more red hues.
Excited to see what you do next
That is for me to know and you to... also know since you asked nicely.
Almost done Members, at which point we'll only have Applications left.
@Nitrate: looks great. Personally I'd work on the character more but that's up to you.
