ideas in Pixel Art

what a hell i just made

2 year's ago i was using this Art Style is it too plain ? or is it enough for a platformer kinda game's. Would love to hear your opinions. I did a lil bit shading couple month's ago not in this picture but still this style seem's a lil too plain.

Very strange guy!

Project from last month, made on Piskel

Random Idea / Logo -> "Furious Force Five" What genre of game would this be?
