The thing that really convinces me is the impact crater that can be seen below clouds. I found a pic of an impact crater on Venus that appears to match up to the impact crater on the daleel pic.
See what you can find. I don't want to bias your opinion too much.
Perhaps you will find other features that may match up.
Check out the Google Image search "venus radar" and see if you can find your impact crater picture there. I still need to see the original OBL pic to make a good comparison.
