I agree with "readable". But it's very far from "comfortable to read". There is plenty of space to enlarge the bubble and the text and it won't hide important detail of the background. So I totally agree with @ IngenuousDaemon enlarging would be a great and easy (compared to 3d modelling) improvement.
Hi all, I am happy that this experience, my 3D works, are appreciated by you. I chose to keep my creations free because I am not a professional, but making them requires commitment and a computer turned on. If you like my works, I only ask you for a little help to keep all this free, > https://ko-fi.com/romolus753 <, thanks.
