Hey my dude! I like the composition & the linework for the floorboard c:
Some critiques I have for this:
- I feel like your work would heavily benefit with more consistent & slightly thicker linework, especially for the character on the couch. Work on more confident strokes (it helps with more smoother lines).
- The anatomy of the character could also use some work, perhaps consider looking up references on how hands look like when holding a phone or resting on something!
- As for shading, soft shading can work! I just think you need more diverse dark & lighter values in your color palette, & to study more about light source <3
Keep it up! Best of luck!
