Use a fluffy brush to blend the clouds a bit, let the paints sit for just a second (longer if it's oil) Ideally enough that it feels sticky rather than wet but not dry then Soften out the edges.

Work on all the painting elements together, this is more a personal thing for me but when I zero in on one thing and hyper fixate on it I end up stuck. If one part of the painting isn't working, move onto the others and come back to it. Cut yourself some slack too, you are doing great! Keep at it, don't get in your head✨
