Of course you can do VFX! That’s a good start you’ve got there.
I also worked on mobile VFX. We used Spine to create awesome 2D animations. We then parented Particle Systems to the animated bones. You should try Spine out!
About the card animation, it feels kinda choppy, but that might be caused by the video recording software. I would suggest you to try out different curves to interpolate those keyframes. Check this website out, I think easeInOutExpo should give the card that extra juice.
As for the chest animation, would be great to try a more exagerated version, take it up to 11! You could hold the chest pressed against the floor for a bunch of keyframes, make it wiggle, and then jump and reach its peak in only a couple of frames. Then hold it up there floating for another bunch of frames, and make it come down fast again, giving it a little bit of bounce when it touches the ground.
What do you think, is there anything I could improve?
Does it match the art style of the screenshot in your opinion?
Also I struggled with colors. Any thoughts on that?
I think the starting animation is pretty weak, but don’t know how to add more impact and energy to it.
It was made in Unity, basically I made a bunch of different animations and particle systems and put them on the Timeline to play them in desired order.
I think timing of coins showing up is a bit off, there’s not enough emphasis on a player getting valuable loot.
I also messed up scaling of the lid in closing animation, it’s all over the place.
But in over all I think I did a pretty good job
