If you're not happy with the image you created, then don't upload it. If you receive compliments for your work, be glad and respect the people's opinions about your work. If I say something is good, I'm not saying it just to say it, I mean it from my heart. Don't belittle my opinion please!
I do appreciate your comment, it's just that not everything i upload is because i like it, its because i hope that others will like it, so when people will say comment such as yours i don't feel like i'm being honest if i simply say 'thanks'
