interesting sig first off i have to say i don't think this color scheme is working at all for this signature just too many colors not enough flow the renders seem to be low quality and no depth i like your brush idea i think it's cool your background is also very plain and your blending effects aren't really working on your renders either your text is alright it's readable but im not to keen on it work with something simpler for now keep practicing keep making sigs you'll improve!
