not bad for your first sig.. tbh I like the c4d's but it doesnt fit with colors, the theme doesnt fit, size doesnt work, and you need a border... but honestly not bad for your first try
oh and btw, if your render is dark, your sig should probably be dark. And try lighting to get the attention of what you want to display as the theme of your signature.
whats with all the nonsence in the back and to the left. it doesnt fit at all. the render is just slapped on there.way to big to be a signature. 3/10 but 6/10 cuz ur a beginner
I do have one tip: somehow blend in your render with the rest of the sig instaed of just pasting it on top. It easist to do this if your render fits a color scheme. But otherwise not bad for your first sig! I'm new to gfx too (but a little farther than my first sig )
