Bacon Art, Oh dear~ Options

[bacon]

Well, I critique people in art but I really can't do art either. x:
Someone suggested me to post some stuff so I will but please bear with me because it really isnt very good.

I am practicing doing some basic realism and proportion but let me tell you its super hard stuff x:

In terms of what I actually draw its mostly monsters concepts and scenes/murals. I mostly practice porportion stuff on paper but again its not really good so oh dear.

Please be super hard and informative with me i really want to improve like super bad in terms of proportion and perspective and stuff.

[Show/Hide] oh gosh terrible perosn

[Show/Hide] bomb head monster thing x:

[Show/Hide] flying head

[Show/Hide] long arm concept

I was working on this a bit but it isnt super good it was just some basic coloring this is actually the first coloring I have ever really done in my life x:
Ive never done shading either x:

Never really finished it just put a coat of lame paint on it

also thanks for everyone who has commented. It would definitely be cool to hear some more comments and stuff to see what i am doing wrong/right.
Its always nice to critique ~o:
