Renan,
In years with defined bumper rules, this would not have been able to meet the "bumpers must cover a minimum of 8" either side of a corner" rule. There is no bumper requirement this year. No one can make a ruling based on a picture, the Inspector at your event will check this over. From the picture, I don't think this violates any rule. However as Jim has pointed out, this will be evaluated under R7 and will be observed for any damage to field elements while in competition.
