First impressions, without reading other comments:
Unless the drawing in your sample video was a personal project or requested to be drawn that way, the sample image you were drawing from had a much smaller chest. I appreciate interpretations and personal styles, but you also have no examples of characters with smaller proportions. If I were looking for an artist for a spread of characters, for example, I would likely skip. Maybe include a FAQ for that? Ex: Can you draw children or elderly characters?
Noticed your examples are also all portrait ratio, as well, which distorts the thumbnails. The wide ratio can enable you to double the number of samples you present, with a bit of editing. Ex:
You might also want to be very careful with the offering of nudes, as that might go against Fiverr TOS. (Non-Permitted Usage)
“And if possible please follow this template below, copy and paste, fill it out, and then send it via private message. This will help me understand what your asking for in your commission.”
‘I’ve provided a simple template below to help with communication for in your commission. Please copy and paste it into a private message with your specifications.’
Continuing, you might want to make the part of the template that’s to be edited not-bold. Ex:
Character Name: (Please state as original or canon/fanart. If canon, specify where its from.)
Next thing that jumps out at me is the request to visit your DA page. Because you’re trying to present your best work, you might want to consider cleaning that up. I went to your ‘Requests’ folder, trying to think like a potential buyer, and I can tell those are older works. (I can say I’m impressed with your improvement, but that’s not what buyers want to see.) Maybe start a ‘portfolio’ account? Not sure what I can offer as a suggestion for that one. (Also, TOS caution.)
Lastly, the section that shows the bit from your profile:
“I also do 2d pixel animation on the side for my indie game group, named 248; currently working on our first 2d Puzzle Platformer, Traversion, using Unity as our game engine. Additionally, I dwell into semi-realistic illustrations and writing my own sci-fi/fantasy novel, but only as practice.”
‘For fun and practice, I dabble in semi-realistic illustration and writing sci-fi/fantasy. I make 2D pixel animation for my indie game group, 248, on the side. We are making a 2D puzzle platformer, Traversion, using Unity as our game engine.’
Hope some of this helps!
