Regarding the picture you posted above, there are lots of issues with it.
The person's outline should have less spikes, meaning it should look smoother.
The black background doenst fit, you should add more elements and make a proper background.
Lighting is soo bad I'm going to say its basicaly non-existant.
Text color and font dont match any of the rest.
Now, about your attitude here:
Pretty much every reply you had you were swearing; no matter where in earth, that will lead to no good.
Secondly, they are only trying to help you. Some do it directly and harsh, others beat around the bush. If you think their opinion is wrong or is unfounded, ignore it. The only purpose is for you to improve, if you think you gained nothing let it be, dont reply to them.
Lastly, if this attitude of yours keeps going, I'll have to report you. You have been warned. Follow the forum's rules.
But above all, be nice to others, that's how everyone should behave.
Enjoy your New Year
I bet you will start swearing at this feedback too.
