No pierson you shouldn't think like that, artists never stop learning, people who critiques are our one of sources for improvements, there's no harm gathering different opinions from different people, we must always be grateful when people are willing to say it out and share their thoughts! Those who are willing to spend time criticizing your works are to be treated with respect; this kind of interaction is beneficial to both parties. So, always be grateful of critiques!
Interesting concept and nice colours, however there appears to be an odd contrast between the buildings and the dessert. The buildings look too sharp by comparison? Also though the ships look cool and add to the viewer's understanding of the picture (its position in time and space etc) the one on the right looks out of place in relation to the composition of the rest of the picture. The second building and the birds also look too dark and it makes the distance between the two buildings look a bit off? Anyhow its an awesome painting and a really cool concept Keep up the good work!
Hi there turnip-slop, thanks for the critique! What you've said really is true, i have some problems with both the scaling and the perspective, i'll try to fix it and try to control the values. Thanks again man!
