The key to animation is patience, especially if you're a beginner animator. I only animated 2D things about 5-6 years ago when Madness Combat was quite popular.
I know how to do animation in theory. To make it look alive, you need to remember about inertia, weight, how the body works together, and so on.
I probably won't be making many new animations because it's a rather tedious process, especially with testing, but it's not that difficult in reality. Again, you need a lot of patience and some knowledge of physics to make the animations look natural.
I'll continue working as is for now.
