Welcome, hope everything with you in this community.
My weakness is clear to me, even though some would find my background is great, my thoughts is always "I could've done better".
Those are my thoughts every time I make a background.
And what is frustrating is how coloring each panel takes long when you're being careful, especially the big ones.
Despite all this, I'm getting the hang of it and someday, approach some more improvement for my content.
