Sweet jesus we have a gif here. I was just gonna blast through a bunch of your work, at least in 2019, but I'll give a few extra words to this. Especially considering you're putting yourself down in regards to your animation skill when you really shouldn't. That's not at all to say there's no room for improvement, but for what this is and what it's trying to do I see no issues and if there are any issues the overall presentation, composition, and artwork at hand is of such a level that it more than makes up for any potential problems with the animation. I'd say the only thing to say about the animation is it could have used a few more frames to make it a bit smoother but that'd be more of an "If you have time" thing and definitely not a requirement - especially since it sounds like you're relatively "new" to doing these sorts of animations. In fact, I think you might be lying about your lack of animation skill. Either to your audience, or to yourself. It's great, and I don't think anyone but the most qualified animation critics would say a damn thing about this and even then, it's because they've probably gone and sat on the largest stick they could find and it's coming out of their mouth and obscuring their judgement and vision. Fuck 'em. This is great.
Fantastic animation, great movement of the flesh being manipulated by the tentacles, just the right amount of detail given to how she is playing with the Nintendo switch's controls such that it's not distracting by either being weirdly out of place/badly animated nor being so well animated that it draws attention away from the...ahem...main assets of the gif.
