I just updated the rules because of XLR8ED's post.
X, your animation has 48 frames which atm is not a big deal, but if someone makes something which is a different non power of 2, multiple of 2 shit will get out of hand fast in terms of frame amount.
Also please do not use different frames speeds, 10fps fixed, 100ms per frame, nothing different. So if you need something longer you make dupe frames of it. Please rework your animation to fit into this, and make it 64, or if you have to 128 frames.
