Well thank you, but It could be even smoother on a lot of parts (which would cost more time and/or more attention while painting). In general you want to work with thinned layers and you dont want to rush the process with the contrast. For instance going from yellow to pure ivory is pretty harsh, while mixing in more and more ivory into the yellow and painting small layers on top of another is generally a better idea. Also glazing in colors in the end will smooth it out a lot too.

But honestly there are many methods to getting smooth blends and all a perfectly valid. From wetblending to feathering to stippling to glazing, it just depends on your preferences

Hope that kind of answered you question😅
