although i didnt see it personally yet, i have the same complaint about yours that i always had about mine. those two upright tubes in the center,,, they look so tall and skinny. i had the same round tubes on mine and i always wanted to change it somehow to look more beefy but i could never figure out what to do that i liked. i am currently re-doing mine and wont make a hood hoop, i wish i had a large table plasma or laser cutter to make plate cuts easier, oh well.
whenever you build your own stuff you always open up for some ppls thoughts on what they dont like or what they would have done,,,, for the record, i think your bumper turned out great. or at least what i have seen of it.
