Watercolor '59 Corvette & Process Pictures

Hello friend! So happy you popped by! 
It is 8:00 p.m. here and I just got home from work about an hour ago. I would like to squeeze in some sketchbook work tonight, as it is my rest day from my evening workouts.
Here is the final '59 Corvette watercolor painting that I finished yesterday. After I finished this, I thought of maybe painting the Cadillac from True Romance (one of my favorite movies) at some point. Any True Romance fans out there? 
This is the second car I have ever painted (the first was the Challenger I posted about before). It took me a long time, especially since I used masking fluid and took my time with it after the pencil sketch was completed. Once I was satisfied with the watercolor, I added some white acrylic paint details. Here are some pictures I took throughout the process. 

​This is what the painting looked like after I let the masking fluid dry (you can notice the rubbery/transparent areas) and painted the first few layers of watercolor paint. By this point, I was already adding darker red values on areas with shadow in them, and I even started using a blue for darkest areas. 
I used my Pocket Field Koi Watercolor Set and used Cadmium Red and Ultramarine Deep. I also used pure black for the tires and other sunken areas in the car.

After I was satisfied with the initial layers of watercolor, I let the painting dry over night and removed the masking fluid the following day. I didn't like how the white lines appeared so thick and obvious, so I took a wet brush and carefully went over these areas to soften them out, using the same paint that was already dry on the paper. Then I messed around with the values a bit more using the same paint colors I mentioned before and also started adding more black details. Can you tell something is missing? I decided to get rid of the car seats and then I ended up regretting it...

Here is the finalized painting with the acrylic paint details. I opened up this picture in Photoshop, cropped it and contrasted it a tiny bit. :)
