sorry to say this wont get in the galley due to the use of blur tools, and the not pixel art background. Also I dont think you can include the nes sprites (like the link, megaman etc) because you did not create them yourself (even if you did modify them with the effects). You can include your own versions of these characters however. The game controllers in the center dont seem to break any rules though, you can submit that part without the background. The gameboy seems to be the best part. Your lightsource is inconsistance and you have some jagged lines and some banding (example, the outline around the gameboy's D-pad). There seems to be a little bit of mixed resolution on the snes controller.
Greetings,
Thank you for all your observations, i'll do better next time. Hardly to say, but there's no way i can compete with all the talented users around. Clearly i'm such a big noob on this lol. Appreciated.
