I don't think it will look odd with no upper cabinets on one side of the kitchen as long as you don't need the storage.. It sounds like you are going for a very open look and so you can always add open shelving if you feel the need for either design or storage.
At a quick glance, are you going to be doing your actual prep work at the prep sink in the island - if so then most definitely put a pull out trash there. The pull-out trash should be wherever you do your prep work for cooking meals. Right now it looks to be in a very awkward spot - not good for clean-up or prep.
Or quick thought - switch the trash-pullout with the 19"bank of drawers by the range. Preferably, it should be in the island by the prep sink.

blfenton, thanks. I honestly had not even thought about putting a trash pullout in the island but it makes perfect sense.

Where is your dish storage? Is it in the "hutch"? If so, that's pretty far to walk when unloading the DW.

Is the refrigerator counter-depth (CD) or standard-depth? The doors of standard-depth and most CD refrigerators must extend out past the surrounding cabinets/counters/walls to be able to open the doors fully to access contents, open bins, and remove bins for cleaning. This means they must stick out approx 6" past those surrounding cabs/counters/walls. This also means you can only recess the refrigerator far enough to have the refrigerator's carcass/box flush with the cabs/counters, not the doors. This affects the aisle widths you show in your layout.

Trash pullout...blfenton already addressed that. I agree, the trash pullout should be wherever the Prep Zone is...and it looks to be in the island in this layout (across from the refrigerator and range, next to a water source, no DW or dirty dishes in the way).

Yes dish storage is in the hutch and I have been concerned about the distance from the DW. Right now it seems someone (DH) is always opening doors and drawers for dishes right where I am working so thought this would solve that problem- just creates another though.
Checked the fridge clearance after reading your post and it will work.
These comments are very helpful-thanks

I would switch the dw and the trash, so the trash is still handy to range, prep, and cleanup area, and anyone looking for dishes in the dw won't be opening it into your work area. It would also get the dw closer to your dish storage.

rhome- that is an excellant idea! I have looked at this plan for months and thought I had exhausted all possible solutions. Its sooo helpful to have "fresh eyes" check it out. Thanks to all.
