Questions on These Two

The lily is just too soft - not only the center but some of the petals. I agree with @Ricky336 about the WB which could be warmed up a tad.

I like the drink image and wouldn't eliminate the bokeh effect of the lights in the background, but perhaps crop it a bit tighter to eliminate the reflection in the foreground on the wood table and the distracting elements on the right side. I feel like this one would pass with some minor tweaks (and a different Moderator).

Hello,

These are my suggestions:

Lilly - Alter the white balance. For me, it is just a bit too green/blue. Increase the tint and temp slider, reduce the highlights, and increase contrast and exposure. I personally don't think you need to increase the DoF.

The leaf directly behind the lotus flower though could be distracting. (?)

Glass - I would increase the exposure, decrease the highlights a bit more, and clone out the distracting lights; it gives a cleaner background! I see you've used f 5.6 this time. A better result than your previous glass picture. 

E.g:

The lilly has a dark halo around some of the pedals. Also the depth of field could have been deeper.
