Constructive Criticism Corner in The Growing Artist Aggregation

I've felt like my drawings have been looking kinda flat, overall my characters look kinda stiff and lifeless,,, can't rlly tell why :P

So I would appreciate some art critique/constructive criticism on it!! (can look at my other posts for my art)

I admit my drawings feel flat and lifeless to me as of late and I don’t know why. I’ll be glad for some criticism.

(The drawings are examples)

Neo traditional key, I made this tattoo a couple days ago, i've been doing great these last few months from 2023/early weeks of 2024, and bought a CPL filter for our photos too! and this is the first tattoo pic with the filter on!art

I saw others drawing König (from CoD) with red eyes instead of his usual grey/green! and I just had too... took me around 20 min-

I need to know if the anatomy looks right!

(PS: Drawing at the bottom is a Santa hat, you can see full drawing on my page)

This is one of the few times I prefer the traditional version over the digital - idk why

Experimenting with some new lineart method, i would love to know your opinions about it.
