Thank you very much for your kind words dear.
Looking at your account, I can safely say that you wont exceed the 2k MMR range on this account. But it also seems that still you are not very good in game. You need to learn and practice a lot for now.
Forget about MMR for almost 6 months. Focus on improving your game for now. As you have shifted from Dota to Dota 2, so you need some time to learn the different mechanics and the tips and tricks of Dota 2. I would also suggest you to scroll through our site and read different useful articles which we have written.
Once you feel that you are very good now. Then make a new account and try again for MMR stuff.
