Ah... even though you said you're 21 (I am currently 22 learned from the internet as well), even though you said you're still searching for what to do (still searching for that myself), it was pleasing to scroll through your sketchbook slowly. Almost feels as if you're having fun with the whole process of "Just go on a journey" and let it unfold.
Shall be bookmarking this sketchbook as a rules of thumb about having fun and keep going no matter what. Keep been you, keep doing, keep practicing Roman.
PS : Love the overall looseness in your way of painting + sketching. Those gestures makes me want to do gestures drawing again, even though I am focusing on landscape right now. Possibly will just introduce such practices with nature elements instead.
