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:

The idea is that there are 4 platforms and 3 gaps and the boss tries to trap you in between the arms so that the head can attack
eventually once you do enough damage the arms will start coming for you
