Here's the deal. This happens every now and then....so..yeah.
I'll give advice, tips, something constructive to a random person. It's not to be judgemental, or to say what they are 'supposed' to do. Its a suggestion... That means it may help, it may not. We are all obviously different as human beings. I would also like to state that judging someone's art is wrong. I, by no means, will judge anyone's art unless of course, its for a contest. That is about the only exception. But for the sake of just random doing it? No.
Here is the difference.
Judging: To look at one work and then to look at another, and pick which is better and more aesthetically pleasing.
Being constructive: Using the fundamentals of art theory, one picks out the small specific pieces that makes art look more aesthetically pleasing and applies them.
Judging: This one looks better than yours!
Constructive: This is one way to fix that to make it look better.
Judging: Your work looks like complete crap!
Constructive: To make this work look more appealing, you could try to work on this or that.
The other thing that bothers me is judging a book by a cover. Yes... I have average to mediocre drawings. I get it. But just because my art doesn't reflect my mindset, which I got, mind you, by learning in professional environments such as universities, art sessions (figure studies and art groups), and my current online sessions, you can't tell me that I don't know my theory. There are obviously things I don't know, and I will always seem very repetitive when it comes to giving advice, but I will not let the sore losers and the people who can't take a nice compliment mixed with a little help ruin my day. I have had several people look down their nose at me, and all I have to say is: Have a good one. I may not be the best, but I am continuing to get better.
The reason: I learn from others, and I listen....even if it hurts my pride.
