Nice job! I like the reflection going on in his (?) glasses. I'm not great at critique, but I think a white oval would maybe suit the picture better than the freedrawn shape Ubelix is in at the moment; the font you've chosen for his name is quite geometric, and a proper shape might match it a little better? Keep it up, though, and post more stuff!
It's nice, I like how cartoony it is. As Knopekin said I recommend using a straight oval to surround the character. The shading on the glasses is very good! Definitely keep on drawing. I can tell already your drawings will get really really good if you keep practicing.
yeah there's yin anf yang, and they make black cats and white bears. :')
