I must combine the following sentences in the most effective way. Is my answer correct?

Sentences:
1. He didn't cover his vehicle with the traditional camouflage.
2. He covered it with his own drawings.

My answer(s) - Not sure which is the best way:

He didn't cover his vehicle with the traditonal camouflage; instead, he covered it with his own drawings.

OR Instead of covering his vehicle with the traditional camouflage, he covered it with his own drawings.

Both are correct, but I like the second one better.

Both of your answers are correct and effectively combine the sentences. Here's an explanation of each answer:

1. "He didn't cover his vehicle with the traditional camouflage; instead, he covered it with his own drawings."
In this answer, you use a semicolon (;) to join the two independent clauses. The semicolon is used to show a stronger connection between the sentences compared to using a period. Then, you use the word "instead" to express the contrast between the two actions.

2. "Instead of covering his vehicle with the traditional camouflage, he covered it with his own drawings."
In this answer, you use the phrase "instead of" to introduce the alternative action. This allows for a smooth transition between the two related ideas. The comma after "camouflage" separates the introductory phrase from the main clause.

Both alternatives are grammatically correct and convey the intended meaning. The choice between them ultimately depends on your writing style and the flow you want to achieve in your overall text.
