A reference on Pinterest

I don't know I feel like the problem I'm recently having is that a lot of my artwork looks flat but I am trying to study making my art not look flat and questioning whether or not I should be learning more Anatomy even though I don't really think it matters to me I don't really know what to do

the pride of a demon

Portrait

Hi, i just couldnt place the eyes and the colors seem a bit weird to me. How can i make it better?

Apocalypse fan art

Another fan art. Is there a problem if I always like to draw fan art? I feel kinda off since the design is already there and I just have to translate it. It kinda feels like cheating. Also, I think there's something wrong with the details and composition. Does it catch too much focus away from the face? And I always feel like my work is so stiff and emotionless, like the piece doesn't carry any emotional weight.

Ente

Mein problem ist die textur der ente mit den federn und auch die schatten, wodurch es das bild keine tiefe bekommt

demon girl

I drew this character from my imagination and I think it looks good, but are there any changes I can make to make it excellent?

Tardigrade

Artemis - DND

The hands are a bit of a rush job, I can't draw noses that look right for what I want my style to be (plus the perspective is off) and I feel the waves in her dress could be better.
