I don't get mad - but putting pictures up with ENB, suggesting it looks like crap is not very nice... it's just how you configure it. It's not ENB's fault the image is not realistic, it's the person who configured it (which is not the ENB developer either). And besides that, most aren't made to be "realistic" as in compared to real life images, but realistic as in "it's a fantasy game".
That ENB doesn't work perfect in some situations, fine, it has to work with directx and ever changing videocard drivers and hardware - not to mention the lighting mod(s) you use. How does the normal game look like with RLO+CoT for that matter? There are a billion light sources in RLO that don't make sense but have been left that way to improve the gameplay or because the engine has limits, skies in CoT are far from realistic as well. There is no way to get "Realistic" lighting in Skyrim because the hardware wouldn't even be able to do it, not even talking about the huge limitation the Skyrim engine has. Still. ENB combined with good lighting mod(s) like RLO + CoT to have interior and exterior light can give you the best results. It just takes a lot of tweaking to get there.
And CoT is not an "ENB" ... CoT is a weather and lighting mod for Skyrim and has absolutely nothing to do with ENB Series developed by Boris.
Btw - I use AO with ENB, and I don't have any of those issues from those screenshots in your OP - so whoever set that up, either didn't set the settings right or simply didn't care. It can also be you didn't set your own Skyrim.ini files correct and are pointing fingers to the wrong person(s)... So you might wanna try and add
To get rid of the shadows around your bow and other close person objects which start to look weird when using AO (water, for instance) - If that works you can post on the Bethesda forums as to why oh why, instead of posting here that ENB and/or AO is junk while it certainly is not.
