My dancing was VERY similar when I first started. I was at a party and a guy came up to me and kind of busted my balls a bit, which was what inspired me to learn more about the actual style of liquid. The terms he used for my stuff were : Too constricted, too many figure 8s, no speed control, and lack of any sort of big moves at all. I felt sort of awkward when it happened, but I was glad it did, as I found Floasis due to the criticism. I would level the same comments at your dance. Others have already stated it, but, work on big rails, and work on speed control and tension. I found that once I opened up the liquid to go all around my body, as well as getting splits/crossovers going, my liquid got a lot less constricted and much more varied.
RE: integrating footwork w/ liquid - This is TOUGH at first... and....later, too. ;) I have a lot of issues with this, and I work on it a lot. As someone mentioned in, I think Birdage's thread, It's counter-intuitive to combine groovy feet with technical arms and hands, so it is always an uphill battle. Occasionally, when I am feeling really loose at a party and have been dancing for hours, it clicks for me, but then I have trouble replicating the feeling/flow the next day. It gets frustrating sometimes, but keep on chuggin.
