Nice, they both seem really good to me!
Things you could add:
COLOUR:
A has employed a limited palette of cool colours, whereas the colours in B are warmer. The flat blue-grey in the background of A suggests depression and a feeling of blankness or loss, and contrasts sharply with the surreal brightness of the pale lemon chair. Conversely, the colours used in B are analogous and generate a sense of harmony, and the cooler tones in the background help to suggest distance and create a depth which is absent in A.
SHAPE
(note...i could be wrong but I'm pretty sure "form" is only for literal forms like sculptures and 3D works. Has anyone else learnt this?)
Although the shapes in both A and B are predominantly organic and flowing, there are some harsh edges in A that create more jagged shapes. The bird and the chair seem almost to be cut out, manufactured, and this technique is strongly divergent to the way in which the shape of the cow in B has been created, as it appears almost fluid. Additionally, despite the blurred edges of the man's head in A, it is clearly composed of geometric shapes, like the other elements in the composition, and the prevalent shapes in this work are rectangles and ellipses. B also employs some geometric shapes, such as the triangle-like mountains, but the work is predominantly composed of more free-flowing, irregular shapes.
There is oblique repetition of the shape of the shapes in A - the chair seems to be echoed in the form of the man's hat. Similarly, balance is created in the composition of B through the shape of the udder which is reflected in the flowing blades of grass on the left of the work.
