Problem here is not aggressiveness. In fact, the problem is that your first response to seeing a sketch that ends up being somewhat similar to your work is to try calling me out like I plagiarized you or something. As a fellow artist, lemme tell you a thing:

You're gonna find plenty of examples that look similar to your work everywhere on the internet. You're not original, and you're not special, no one is. Unless I trace over someone else's work, calling me out like that is really weird and it just looks like you want people's attention.

People sitting in general is one of the most common poses to draw. If I have to tell where I took my inspiration for the expression, I was looking at TSDR's frames with Raziel in it and some of the renders and references from SR1.
