Yeah I'm just going to say my own opinion of what I feel. I feel that since you draw just about the same thing for the longest time you have been on here, you have lost some ideas on what to draw with that same theme. Pony anthros is something that a lot of people relate to you here, but if you try to draw some other things once in a while, like trying to make something related to space exploration, robots, or even some pirates having a jolly time aboard a vessel, then you can try to find some of that creativity to make something with your ponies again. It's something everyone goes through, especially when they go through a phase like MLP, then they might even get TIRED of it. So you might either need to expand and broaden your horizons, take a permanent break from ponies, or try to make a change of scenery or a break from the entire thing altogether.

This is just my opinion, so I hope this helps. G'day.
