The model itself isnt of great quality, but it is a start. The most important thing is to take all the negative comments and think, "What could I fix about my model that would make it more appealing?". If you do this you will never be lacking of something to do. It takes time to make great models, and it takes effort. I recommend you try a free app instead of a trial of a powerful app's trial before you really get into the modeling trade. I still havent even tried any paid programs, I'm still using Wings 3D and it suits my tastes. Find a modeling program that you like the way you use it. Stick with it, ignore blatantly rude comments about your models. Listen to people who critisize your models and find out what you can fix to make it appealing. But, don't be a conformist, just keep in mind there is truth to the criticism.
