Wow. This is beautiful.
Finally, I have met a second person who sketches with a pen. All this while I only knew one person that loves sketching with pen and I always admire his works.
So that makes you the second person.
This is so cool and I like his wink and how he squeezed his lips lol.
You say you aren't professional but this is already looking so good and I wish I can sketch with a pen as well.
I love drawing too but I only make a simple pencil sketch.
