Note: This sketch was updated as I had recorded the wrong EP and magnification used while observing.
Here is a sketch of a Globular Cluster M15, found in Pegasus, from last month that I finally got around to digitizing.
This is actually a very bright GC, and one that had a lot of well resolved stars and a very bright core. There is also a bright, yet diffused glow that encompasses 3/4ths of the GC due to the many bright stars in this compact GC.
Rare among Globular Clusters, M15 contains a planetary nebula (which I did not observe/see). One of the better GC's in regards to well resolved stars and brightness, M15 is definitely worth slewing your scope in its direction and taking a look.
Here is how M15 appeared to me through my EP:

Wade,
What I have always enjoyed about this globular is that dense core. You have done a marvelous job capturing it. Love the sketch Wade.

Nice drawing of a favorite globular cluster. It's funny that it resembles the view in my 10-inch at 375X when the seeing is very calm. I've never seen the planetary, it's about 1 arc second in diameter and it takes very high magnification to see amid the other stars. I have however seen the star like inner core of this globular cluster where a black hole is spewing out X-rays from it's accretion disk. You must have had both a very steady night and sharp eyes to see that many stars with a medium power eyepiece. M-15 is definitely one of the best objects in the sky for small and big telescopes alike.

Taras,
Thank you for pointing that out. I had the wrong EP and magnification listed on this digital rendering. I have corrected the information. 
Thank you everyone for all the kind words. I find Globulars extremely challenging and fun to sketch due to the sheer number of stars. For me anyways, a Globular can easily become a muddled mess, therein lies the challenge of sketching these wonders of the night sky.

Wade,
What an impressive sketch of a majestic globular with a blazing heart!
Keep them coming.

Nice rendition! I haven't seen M25 in quite a while...and would love to check it out tonight, but we got swamped in with cloud cover here in Oakland.

Wade,
What can I say... I thought I was looking through the eyepiece with you.
All these wonderful sketches I see have made me a regular visitor to this forum and I've started to practice the ART.
Thank you.

Wade,
An excellent observation of M15 (NGC 7078) in Pegasus. This globular cluster appears to "explode" in the eyepiece field. Thank you for sharing it with us all.

Thank you Carlos.
You are correct in that M15 certainly does seem to explode in the EP. Oddly enough, it was M15 that was my first GC that I ever found back when I got my first scope. Of course, at that time Pegasus was one of the few constellations that I didn't need my planisphere to find neither.
