If there was ever a way to cram as much happiness as possible into one artwork, you have certainly figured it out! Melody is such a bundle of sweetness and joy and I think you captured that so beautifully here! Her expression
gives me life energy, it is so radiant with positivity aaaaghhh~! I really really like how in all the lines, even the nose and eyes and especially the hair- there are sooo many different colors! It makes the artwork feel so rich and engaging! All the pink hues you used in the shading really compliment the blues in her design and make her otherwise-dull palette into a bright and fun one! And the use of pink also goes really well with the reds of her flower, as do the little hearts on the side~! I really love when artists give their all in the coloring and are willing to take on creative color choices like this >w< the petals on the flower, by the way, are amazing!!! And the stripes and piano keys on the scarf are perfection!! This is just such a beautiful art, I will cherish it ferociously
also, I don't know how to describe the effect but there's this like... roughness? with the pixels? on the edges of colors? I don't know if it is a brush thing with how you do your brushes but it gives me the nostalgic feeling that pokemon mystery dungeon character icons have and it makes my heart feel all soft and mushy with nostalgia <3 <3 <3 your sketch art I just adore! I love your normal art too, of course! But this nostalgic look makes my heart very happy aaahh
