@Mihai, well done! I really like the rectangle. There's some interest in the glaze that adds an element of texture without being too busy. I almost think that your layered corner pot could have done with a more striking glaze - not necessarily brighter, but just something to make the pot pop a little. I think the combination of the glaze being dark and matte maybe a little too subdued. Perhaps a medium blue or a dark green would have shown off the interesting structure a little better. Some slight texture like your rectangle pot would have been nice in the dark glaze as well. Both pots' feet are proportional and help them feel grounded. A lot of potters (especially new ones) don't pay enough attention to the feet. Although your pots' feet are plain, they compliment their overall structures.
Could you post a view from above for both pots? Seeing the wall alignment will give an indication as to whether you need to adjust to ensure the walls are straight. Many potters (myself included) have trouble sometimes with walls bowing and warping. Those kinds of details matter when someone picks up your pots.
Either way, you've put together some really nice pottery. I hope you have plans to continue, because you seem to have a knack for working with clay. These pots look lightyears ahead of someone who has just began working with clay. Seriously, well done.
