You just have to go at your own pace, this is your comic and we have over billions of people in the world. Not every single one is going to like it, but just as many people would dislike your work. The other half are going to praise it, enjoy it and want more. Looking at other people stories should be your attempt to see what they do right, but not to copy them. If you feel your work is beneath what you want it to be, there will only be self conflict.
Just keep moving forward with your story, make it the way you envision and never stop to change it just because someone wants to see something different.
Personally I look through other comics because I enjoy the tale they spin, but I want to do better then them. No matter how many people say it's the best comic/story/etc. I want to write an even better tale, a challenge brings out the best in the person is what I believe. So it's how I usually overcome this with a good old fist Fight!
