looks fine to me also...

you can easily check and set your monitors settings using the graphics on this page, it wont make it perfect, but it will really get your monitor close to what you should be seeing

Trust........your workflow!

Hardware calibration and profile generation is really the only reliable method. The easiest thing to calibrate is a CRT, but they drift over time (and who has one anyway?). LCDs and LEDs are problematic because they are way too bright for photo work. This can be taken care of if you measure the brightness (with a hardware calibrator) and dial down to about 100 - Cd/m2, depending on the ambient lighting. Do not have the monitor at it's default brightness (~200 cd/m2), cause if you process your photos like that, any prints you try to make will be dark. Another problem with LEDs and LCDs (especially cheap TN panels), is narrow viewing angles and variations across the panel. IPS panels are much better for calibration, and they are getting better all the time. I used to have a "good" NEC LCD but it was a bear to calibrate. I now have 2 Dell 22" IPS LEDs that calibrate like a charm and they are virually identical. The fundamental step in any decent workflow is to make sure that what you see is reproducible.

Another problem that rears it's head all the time.........->Unfortunately there are'nt enough commonly used applications that honor embedded color spaces and display them correctly. Among the culprits are...Internet Explorer (prior to 9), MS Paint, MS Word, Windows Photo Viewer. These applications assume that the photos they are displaying are in the sRGB color space, regardless of the tags that are embedded in the file. This can cause major color shifts, especially if someone post a photo in the Adobe RGB color space and it is viewed with one of the applications I have listed above. Chrome honors color space, but not at it's default state. You have to set it up that way, but I can't remember how as I don't use Chrome. Safari and Firefox are color managed browsers.  The only saviour for most people is the fact that the default profile that most standard monitors is "loosely" designed to match sRGB. This helps, but it's just not enough for critical color work.

The result of this failure to calibrate and profile is.....you don't see what I see and what you are intended to see.

This is a long and complex subject, but there are plenty of resources out there that can explain better than I...

Try this for a primer...http://photo.net/learn/digital-photography-workflow/color-management/
