please don't invite me to any topics, I don't even have a lot to say for such a subjective question like this. if you want advice from people, inviting them to topics that don't directly involve them might not give you the help you need.
as for your original question, I think Yulek gave enough info to help you. looking "hot" is going to depend on how you portray him, and everyone's personal preferences range too.
Lots of people think Tom Cruise is good looking, but I don't. Your character personally doesn't interest me, and looks very average, but maybe he is attractive to someone else.
Try studying at the physical features of drawings/references that you're trying to go for. From your images, it looks like you like sharp, young, boyish features instead of strong, heavy ones. Eyebrows, eye shape, and facial structure are important.
