Welcome to Gaia! ::

thats an awesome concept for a drawing.

well another thing for the hands is that the fingers don't all start level. they are situated in an arch. with the middle finger being the highest and in the middle of the hand. also with hand on the pinky side it doesn't angle out as much. it is more parallel with the index edge. (hope that made sense). the hand nearest to the flower(the semi closed one) the thumb should be alittle further back. unless its not in the relaxed position, then you should put some creases to show that its being pulled to the foreground.

the second drawing is really good too. i really like the way you shaded it and showed highlights. i also feel that its a very strong piece for its limited color palette only thing i see that is weird to me is the hand. they way shes holding out there just feels awkward and weird and i tried to put my hand in that position and it kinda hurt. lastly the base of the thumb should alittle protrude more

but i really like your stuff you seem to have a good understanding of light and a sense of design and detail
