Hi Rénaldi, Nice work, i don't know much about inking, but i like your style and i think it has a lot of potential. As for improving your craft, my advice for you would be to simply work on the fundamentals. I see many problems of anatomy, placement and volume in these drawings (this is especially visible on the second one). And all of it seems to stem from a lack of understanding of the human figure. I don't know if you've taken the Figure Drawing course, but i feel like it would greatly benefit you. Hopefully this was helpful. Again good work, keep going! ;)

These are all looking pretty decent already! I won't be able to free hand like this. I can imagine this kind of style fitting on some murals and stuff like that. Do you have certain style or artist's work that you are looking to achieve? So that people will be able to know what still needs improvement :D

Woow ! Your characters are so cute and cool ! I really like their hairs. For an idea of improvement, I hope I don’t say anything wrong, I am not a very advanced artist : I think the stones at the left of the first drawing have too much line weight/are too black and I think the shadow under the right hand should look like fingers? (I don’t know much about shadow though). Otherwise, I agree with Peter, all your characters look lovely, it would be nice to know more about their story !

These are lovely. Have you studied Alphonse Mucha's drawings at all? Arthur Guptill's Rendering in Pen and Ink would also be great if you haven't read it. On the male, the digastric plane looks strange. Steve Huston has a 3 hour Youtube video on head drawing, where he talks about this. You don't need to watch the whole thing, just where he discusses the profile view. My main problem with these is the backgrounds are coming forward too much. Look at these from far away, and you'll see that the figure disappears among the background in the first and last. You really don't need a lot of detail in the background, just simple and characteristic shapes. I think if you do that, these will real much clearer from a distance, as the figure will have a much clearer silhouette. You could also do this with values (light subject, dark background or vice versa). Aside from the technical notes, I'd ask yourself more about the characters you're drawing, who they are, and what the story is
